Well, doesn't look like that at my site.
OK, that was simply bullshit.
I just tried it with adding the xcom-original-files, and voilà: The game has quite a lot of sounds more. Only thing I was missing, is the trippling-sound of moving units. But if that's the only thing going not so well, I'm rather satisfied. =) And also I just tested the server, which seems to be running quite smoothly, actually. OK, I just did two little matches against myself. ;-) But it worked quite well!
So I am considering some kind of offer for the community: I might let my homeserver run for, lets say, a month. Starting at an announced time, e. g. 1st of march, or something like that. It will actually cost myself some money, as I have to pay the electricity-bill. But I'm willing to do so, in order to give the people some place to play and push the game a little. It might not be as comfortable as the original one was. For instance, I have no idea of how to add this very nice elo-score-query, the original server had. But it'd give a platform for playing the game once again, at least for a while. I may not be a good enough programmer, I have no graphics-skills whatsoever, but that would be the least I can do. I loved playing this game and I'd love doing so again.
But this all depends on, if there is actually some demand. If there are only three people willing to play, the more economic way would be, to arrange virtual meetings at a certain time.
Anyone interested?
